Sargassum high-efficiency cultivation and in-situ utilization method

Abstract

The invention discloses a sargassum high-efficiency cultivation and in-situ utilization method. Sargassum is cultivated in a net cage, the root of the sargassum is fixed at the bottom of the net cage, choice rare sea food preferring the sargassum is poly-cultured in the net cage at the same time, the net cage is hung in seawater to feed the sargassum and the choice rare sea food, and culture density of the choice rare sea food is controlled to make the feeding rate of the choice rare sea food not larger than the growth rate of the sargassum. By means of the sargassum high-efficiency cultivation and in-situ utilization method, sargassum culture, harvest and processing and choice rare sea food culture are combined and simplified to one step, so that risk in sargassum culture and processing and marketing links is reduced greatly, and labor inputs are reduced. Furthermore, by means of the sargassum, a system environment can be controlled effectively, and survival and growth of the choice rare sea food are facilitated. The cultured sargassum serving as alive bait is free of artificial ingredients and good in quality, the choice rare sea food cultured by means of the sargassum is green and free of pollution compared with choice rare sea food cultured by means of dried sargassum, therefore, the choice rare sea food is favored by consumers, and high economic benefit can be created.

Description

Technical field: [0001] The invention relates to a method for high-efficiency cultivation of sargassum, in particular to a method for high-efficiency cultivation and in-situ utilization of sargassum. Background technique: [0002] Sargassum is widely distributed along the coast of my country, and is an important industrial raw material and high-quality feed for marine treasures. In recent years, with the rapid development of my country's aquaculture industry, the demand for sargassum in the domestic market is increasing. However, due to factors such as environmental pollution and excessive collection, the resources of sargassum in natural sea areas are increasingly depleted. Therefore, measures must be taken Effective methods for its artificial breeding. Artificial cultured Sargassum has the advantages of fast growth, high feed value and less mucus, and its breeding technology has become increasingly mature. However, the fresh sargassum cultured generally cannot be used dir...

Problems solved by technology

However, the cultured fresh Sargassum generally cannot be used directly. Basically, the algae are dried or dried for storage or deep processing. The whole process is time-consuming and laborious.

[0003] During the cultivation process of Sargassum algae, with the continuous growth of its algae, the local density will become larger and larger, and the surface layer of algae will block the sunlight, which is not conducive to the growth of the lower layer of algae, especially in the later stage of cultivation, because the lower layer of algae cannot get enough The sun will rot and fall off, which greatly reduces the breeding efficiency; the sargassum breeding process will also be damaged by harmful organisms such as basket fish; in addition, the harvesting, storage, transportation and processing of the algae require a lot of manpower and material resources, especially in the coastal area of ​​South China, the main producing area of ​​sargassum, due to the hot and humid climate, the sargassum stored in the sun is particularly prone to moisture and mold, which greatly reduces its utilization value
